Background and Objectives |
| |
Compared with normal TV or even HDTV, a viewer would get a heightened sensation of reality from the ultrahigh-definition video system under development at STRL. Its large, wide-view screen has a resolution equivalent to that of gravure printing. Over the last year, enhancements were made to all of the early prototype's imaging, recording, display, and audio systems. To assess the effects of the large, wide-view screen, we produced programs mainly composed of motion pictures. |

Features |
| |
- Standard Specification: The video format of the 4,000 scanning line system has four times the number of pixels of the Hi-Vision (HDTV) standard, both vertically and horizontally, and uses progressive scanning.
- Imaging system: To pickup images suited for a wide-view/large-screen display more efficiently, we are developing a compact camera.
- Recording system: A new recording device that employs parallel HDTV hard disks was fabricated, expanding the recording/playback time to 18 minutes, from the previous 34 seconds.
- Display system: Automated data acquisition realized highly accurate geometric compensation for the projector.
- Audio system: In an attempt to create new sound effects, additional loudspeaker arrays were installed at either side of the screen in order to control the perceived distance of sounds. |

Future Work |
| |
Psychological effects, such as the sensation of reality perceived from ultrahigh-definition/wide-screen images and three-dimensional sound, will be examined quantitatively, and the results will be used as basic data for future broadcasting endeavors aimed at delivering an unparalleled level of realism to viewers. Development will proceed with an eye to performance improvements on the systems that will be needed to achieve this goal.
